#3371: Spurious "Defined but not used" when using record wildcards
-----------------------------+----------------------------------------------
Reporter: Baughn | Owner:
Type: bug | Status: new
Priority: normal | Component: Compiler
Version: 6.10.3 | Severity: minor
Keywords: | Testcase:
Os: Unknown/Multiple | Architecture: Unknown/Multiple
-----------------------------+----------------------------------------------
Code such as
{{{
{-# LANGUAGE RecordWildCards #-}
module Test(bar) where
data Foo = Foo { a, b :: Int } deriving(Eq)
bar Foo{..} = print a
}}}
produces "defined but not used" warnings for both a and b, when compiled
with -Wall.
The expected output is that either only a warning for b is given, or none
is given.
